The fully mixed lithium-rich liquid is divided into an upper oil phase and a lower water phase under the action of an organic phase extractant, the oil phase loaded with lithium is collected through an overflow port 1 and then returned to the lithium-rich liquid circulation tank, and the lithium-poor raffinate of the water phase is pumped from a water outlet 2 to the electrodeintercalation equipment by a centrifugal pump for electrodeintercalation and delithiation circulation. After the cycle of the electrical deintercalation and the delithiation is finished, the loaded organic phase is all led into a circulation tank, the lithium complexed by the organic matters is back extracted into the clean water, and the regenerated organic phase is used as an extractant for the next cycle.
The Wu Youni brine is taken as raw brine, and the circulating tank of the traditional electric stripping and embedding device is compared with the circulating tank of the lithium-rich liquid with the same volume provided by the utility model, so that the effect of the device is further described.
2 parts of Wu Youni brine is circulated in the electric stripping and embedding equipment for 8 hours, the circulation flow is 20 parts, the current density is 25A/m < 2 >, the voltage is 0.35V, and the total electric quantity is 5100Ah. The indexes of the lithium-rich liquid obtained by adopting the common circulating tank and the back extraction lithium-rich liquid of the circulating tank provided by the utility model are shown in table 1:
tables 1, wu Youni brine and lithium-rich liquid chemical composition (Unit: g/L)
As can be seen from Table 1, the electrical deblocking device had the disadvantage of low efficiency, and only 1000.+ -.100 g of lithium ions were extracted from one device over a 12 hour period, and only the electrical deblocking conversion was 9600 degrees of electrical/mt LCE.
In addition, the traditional circulating tank has the advantages that because the dead volume of the pipeline and the coating material in the machine body contain gaps, lithium-rich liquid can remain on the polar plate, 800+/-80 g of lithium ions can only be recovered on the lithium removal side each time, and the residual lithium ions need to be washed with clear water for many times, enter washing water and do not enter the lithium-rich liquid. And the traditional circulating tank is adopted, the Na/Li ratio of the lithium-rich liquid is still higher than 2, the subsequent impurity removal cost is quite high, and the power consumption of the whole process is as high as 14000-20000 ℃. This is one of the main reasons why the existing electrical detachment can not be used for industrial production.
By adopting the circulation tank provided by the utility model, the deintercalated lithium is timely enriched under the condition of low concentration, and the lithium precipitation qualified liquid is further enriched after separation, so that the objective lithium removal speed is also accelerated, and the whole circulation time can be reduced by 2 hours (the running time is reduced by 17%). In the ten hours, the back extraction/lithium precipitation operation can be performed every 3 hours, so that the construction period is shortened.
The circulating tank provided by the utility model solves the problem of lithium-rich liquid residue, and because the extraction technology adsorbs lithium ions in the tank body in time, no polar plate residue and dead volume residue exist, and the lithium removal amount and the lithium intercalation amount of the circulating tank provided by the utility model are almost balanced.
The foregoing is merely illustrative of specific embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any changes or substitutions within the technical scope of the present utility model should be covered by the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
